Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a rescue knife with a light. Background Technology

[0002] In maritime emergency rescue scenarios such as ship accidents and floods, rescue knives serve as multi-functional tools, primarily used for underwater demolition, cutting entanglements, and emergency escape operations. For example, rescuers may need to cut ropes, fishing nets, or aquatic plants attached to drowning victims, or break through obstacles on the hull of a vessel in murky water to create an escape route.

[0003] Currently available conventional rescue knives are mostly presented as simple blades. Their design focuses primarily on basic functions such as cutting and slicing.

[0004] However, in dark environments, such as at night or when working in the hull of a shipwreck, rescuers need to carry additional lighting tools, such as flashlights, when using a rescue knife. This not only increases the burden of carrying tools but also makes operation inconvenient, as they may need to hold both the rescue knife and the lighting tool simultaneously, affecting the efficiency and convenience of the rescue work.

[0005] Therefore, there is an urgent need for a rescue knife that integrates lighting, cutting and other functions to improve rescue efficiency and reliability. Utility Model Content

[0042] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] See Figures 1 to 8The rescue knife with a light provided in this embodiment of the utility model includes a blade body 1, a handle 2, and a sheath 4. At least one side of the blade body 1 forms a blade edge 11; the handle 2 is connected to the tail end of the blade body 1 and is equipped with an illumination component 3 that emits light; the sheath 4 can be fitted onto the blade body 1 and is equipped with a locking mechanism 5 for locking the sheath 4 to the blade body 1.

[0044] The rescue knife with integrated lighting proposed in this utility model features an illumination component 3 on the handle 2, eliminating the need for additional lighting tools when using the knife. Users can simultaneously perform cutting and illumination functions with one hand, significantly improving ease of operation. A blade 11 is formed on one side of the knife body 1, providing basic functionality for cutting and slicing operations. The sheath 4 is equipped with a locking mechanism 5, which locks the sheath 4 to the knife body 1, ensuring the knife body 1 is securely stored in the sheath 4 when not in use, preventing accidental dislodgement, improving safety, and avoiding injuries or equipment damage caused by the knife body 1 shaking. It is also convenient to carry and store, comprehensively optimizing the user experience of the rescue knife with integrated lighting. In summary, this rescue knife with integrated lighting, through the coordinated design of the knife body 1, handle 2, illumination component 3, sheath 4, and locking mechanism 5, not only simplifies the tool structure but also combines lighting and protection functions, providing reliable illumination and safety in various usage scenarios.

[0045] The specific structure and working principle of this rescue knife with light will be explained in detail below.

[0046] The blade 1 serves as the cutting body of the rescue knife with a light. At least one side of the blade 1 forms a cutting edge 11, which is used to perform cutting and slicing operations to cut ropes and cut through obstacles, thereby opening up a rescue channel and rescuing trapped personnel.

[0047] Specifically, the blade body 1 can have blades 11 formed on both sides, so that the user can obtain the same sharp cutting effect regardless of which side they are used to during operation. This increases the flexibility of the cutting operation and eliminates the need to frequently change the direction of the blade body 1 when dealing with cutting needs in different directions or angles, thereby improving cutting efficiency.

[0048] Alternatively, one side of the blade 1 forms a cutting edge 11, and the other side forms a serrated saw blade 14; the cutting edge 11 is suitable for conventional cutting actions, while the serrated saw blade 14 can be used to cut thicker and tougher materials, such as thicker branches and ropes, more efficiently, expanding the scope of application of the rescue knife and enabling it to deal with obstacles of more different materials and shapes.

[0049] Alternatively, one side of the blade 1 can form a cutting edge 11, while the other side can form a blunt edge. The blunt edge can be used for some non-cutting auxiliary operations, such as tapping or pressing, to prevent the cutting edge 11 from being damaged in these operations. It also provides more diverse ways of use and enhances the overall functionality and practicality of the rescue knife.

[0050] In actual use, the specific structure of the blade body 1 can be adapted to actual needs, and the specific form of the blade body 1 is not limited here.

[0051] Optionally, serrated anti-slip teeth 13 are formed on the portion of the blade 11 near the handle 2. When the blade 11 contacts the object being cut, the anti-slip teeth 13 increase the friction between the object and the blade 11, preventing the blade 11 from slipping or deviating, thereby reducing the risk of accidental injury caused by the blade 11 sliding and improving the stability of the rescue knife during use.

[0052] Optionally, the front end of the blade body 1 forms a pry bar 15, which extends parallel to the width of the blade body 1. The pry bar 15 expands the functionality of the rescue knife with a light. In actual rescue or usage scenarios, when it is necessary to pry open obstacles or open enclosed objects, the pry bar 15 can be used as a lever. Utilizing the lever principle, a large prying force can be generated with a small force, making it easier for rescuers to pry open objects such as door and window gaps, box lids, etc. The lateral extension structure of the pry bar 15 increases the force-bearing area in this region, dispersing stress when subjected to prying pressure and reducing the risk of deformation or breakage of the blade body 1. At the same time, by using the pry bar 15 instead of a sharp blade tip as the contact point at the front end of the blade body 1, the risk of accidental stab wounds to the object being operated on or the user is reduced during prying, making it particularly suitable for use in confined spaces or close-range rescues. For example, if the rescue knife is accidentally dropped, the laterally extending pry bar 15, without a sharp point, is less likely to damage fragile objects such as inflatable lifeboats, improving the safety of the rescue knife.

[0053] The sheath 4 is fitted onto the blade 1 to prevent injury to personnel or damage to equipment caused by the shaking of the blade 1 during carrying, and to facilitate carrying and storage.

[0054] Understandably, the internal structure and shape of the sheath 4 are designed to fit the blade 1, so that the sheath 4 can completely protect the blade 1. Furthermore, the sheath 4 has a symmetrically designed accommodating space about the blade 1, allowing the blade 1 to be smoothly inserted and secured to the sheath 4 regardless of whether it is inserted from the front or back. This caters to the needs of operators with left-handed or right-handed usage habits, improving the adaptability and flexibility of the rescue knife.

[0055] In addition, multiple ventilation slots 42 are provided on the side wall of the sheath 4. The ventilation slots 42 can promote air circulation. When the knife body 1 is put into the sheath 4, air can enter and exit through the ventilation slots 42, avoiding the formation of a closed and humid environment inside the sheath 4. This effectively reduces the possibility of the knife body 1 rusting due to moisture and extends the service life of the rescue knife.

[0056] To prevent the sheath 4 from detaching from the knife body 1 during carrying or movement, thus avoiding a safety hazard, the sheath 4 is equipped with a locking mechanism 5. This mechanism locks the sheath 4 to the knife body 1, ensuring the knife body 1 is securely stored within the sheath 4 when not in use. This prevents the knife body 1 from accidentally detaching and sinking under conditions of ship movement, diving, or strong currents. Especially during underwater operations, the locking mechanism 5 ensures the tool is always securely carried, preventing delays due to equipment loss, and avoiding accidental detachment of the knife body 1, thereby improving safety.

[0057] Specifically, the blade body 1 has a locking hole 12. The locking mechanism 5 includes a locking shaft 51 and an actuating structure 52. The locking shaft 51 is mounted on the sheath 4 and extends along its thickness. The actuating structure 52 is used to drive the locking shaft 51 to insert or retract from the locking hole 12. The locking shaft 51 is mounted on the sheath 4, making the locking structure more compact and reasonable, occupying less space, and not affecting the overall aesthetics and portability of the sheath 4. The actuating structure 52 drives the locking shaft 51 to insert or retract from the locking hole 12, making operation simple and convenient. When the locking shaft 51 is inserted into the locking hole 12, it can firmly lock the blade body 1 inside the sheath 4. Even under violent shaking or bumping, the blade body 1 will not accidentally come out, ensuring safety during use and preventing accidental injury caused by the blade body 1 coming out. When a rescue knife is needed, the actuating structure 52 can easily retract the locking shaft 51 from the locking hole 12, making it convenient to remove the blade body 1.

[0058] Optionally, the actuation structure 52 includes an unlocking lever 521, a first return spring 522, and a second return spring 523. The unlocking lever 521 is disposed on both sides of the locking shaft 51. When the two unlocking levers 521 move toward each other, they can push the locking shaft 51 out of the locking hole 12. The first return spring 522 is disposed between the locking shaft 51 and the inner wall of the sheath 4, and is used to return the locking shaft 51 to its initial position. The second return spring 523 is disposed between the locking shaft 51 and the unlocking lever 521, and is used to return the unlocking lever 521 to its initial position.

[0059] When the user needs to remove the blade 1, they push the unlocking levers 521 located on both sides of the locking shaft 51 inwards, causing them to move towards each other. At this time, the unlocking levers 521 push the locking shaft 51 against the force of the first return spring 522, disengaging it from the locking hole 12 on the blade 1, allowing the blade 1 to be removed from the sheath 4. After use, the blade 1 is inserted into the sheath 4. When the locking hole 12 aligns with the locking shaft 51, the first return spring 522 pushes the locking shaft 51 into the locking hole 12, locking the blade 1. Simultaneously, the second return spring 523 returns the unlocking lever 521 to its initial position after it pushes the locking shaft 51, preparing for the next unlocking operation.

[0060] This actuation structure 52 design makes unlocking simple and ergonomic; unlocking is easily achieved by pushing the unlocking lever 521, making it convenient and quick. The first return spring 522 ensures the stability of the locked blade 1. Under no external force, the locking shaft 51 can reliably remain within the locking hole 12, ensuring that the blade 1 will not accidentally come out, thus improving safety. The second return spring 523 allows the unlocking lever 521 to automatically return to its original position, eliminating the need for manual adjustment and facilitating future use, thereby improving the overall smoothness and convenience of operation.

[0061] In other embodiments, the actuation structure 52 can also be a rotating dial. A rotating dial is provided on the side of the sheath 4, and the rotating dial is connected to the locking shaft 51 through a transmission structure such as a threaded drive or gear drive. When the dial is rotated, the transmission structure drives the locking shaft 51 to move along the thickness direction of the sheath 4, inserting or retracting into the locking hole 12, so as to achieve the locking and unlocking effect between the blade 1 and the sheath 4.

[0062] It is understandable that the specific implementation of the action structure 52 is not limited here, as long as the relative movement between the locking shaft 51 and the locking hole 12 can be achieved.

[0063] In addition, an elastic clamping plate 41 is provided on one side of the scabbard 4. The elastic clamping plate 41 and the side wall of the scabbard 4 together form a U-shaped clamping space 411. The clamping space 411 has a clamping opening 412 that is closed under normal conditions. When an outward pushing force is applied to the elastic clamping plate 41, the clamping opening 412 opens.

[0064] In use, when it is necessary to secure the rescue knife to an object such as a belt, backpack strap, or moley, place the object to be secured near the clamping opening 412 of the clamping space 411 formed by the elastic clamping plate 41 on the side of the sheath 4 and the side wall of the sheath 4. At this time, the user applies an outward pushing force to the elastic clamping plate 41, which opens the clamping opening 412, which is normally closed. The object is placed into the U-shaped clamping space 411. The pushing force on the elastic clamping plate 41 is released, and the elastic clamping plate 41 returns to its original position due to its elasticity. The clamping opening 412 closes again, thus firmly clamping the object in the U-shaped clamping space 411, thereby securing the rescue knife to the object.

[0065] With the cooperation of the U-shaped clamping space 411 and the elastic clamping plate 41, the rescue knife can be easily fixed to various suitable objects. For example, rescuers can conveniently clip it to their belts for easy access during operations, eliminating the need for a special knife sheath attachment device, saving space and making it easy to carry. Meanwhile, the normally closed clamping opening 412 ensures that the rescue knife will not accidentally fall off the fixed object when not actively opened, ensuring safety during carrying. Furthermore, the design of the elastic clamping plate 41 allows the U-shaped clamping space 411 to adapt to objects of different thicknesses, improving the versatility of the rescue knife fixing method and meeting the needs of various usage scenarios.

[0066] The handle 2 is connected to the tail end of the blade body 1. The handle 2 is equipped with an illumination component 3, which can emit light to illuminate the blade body 1 or the surrounding environment.

[0067] Specifically, the lighting component 3 includes a lamp 31, a battery 32, and a circuit structure 33. The lamp 31 is located on both sides of the handle 2, and the battery 32 is located inside the handle 2. The battery 32 and the lamp 31 are connected through the circuit structure 33. Positioning the lamp 31 on both sides of the handle 2 provides illumination from multiple angles, more comprehensively illuminating the knife body 1 and the surrounding operating area, avoiding blind spots, and providing sufficient and uniform light for users to perform cutting and slicing operations in dark environments. Placing the battery 32 inside the handle 2 effectively utilizes the space, making the overall structure of the rescue knife more compact and reasonable, without adding extra volume or weight, making it easier for users to hold and carry. It also improves the rescue knife's waterproof performance, preventing the battery 32 from coming into contact with water and causing a short circuit when operating in underwater environments.

[0068] The battery 32 can be detachable for easy replacement, ensuring the rescue knife has sufficient power and offering high flexibility and convenience. Alternatively, the battery 32 can be rechargeable, allowing it to be charged as needed to maintain its power, thus improving economy and energy efficiency. The circuit structure 33 supplies power from the battery 32 to the lighting lamp 31. The specific structure and working principle of the circuit structure 33 will not be elaborated upon here.

[0069] Furthermore, the front end of the handle 2 is provided with an induction switch 34 that is electrically connected to the lighting lamp 31, and the sheath 4 is provided with a sensor 35 corresponding to the induction switch 34. The induction switch 34 can control the lighting lamp 31 to turn on or off based on the relative position of the sensor 35.

[0070] When the rescue knife is inserted into the sheath 4, the sensor 35 on the sheath 4 approaches the sensor switch 34 at the front end of the handle 2. The sensor switch 34 detects the change in the relative position of the sensor 35 and controls the light 31 to turn off, avoiding unnecessary operation of the light 31 when the knife is in the sheath 4 and saving power. When the rescue knife is pulled out of the sheath 4, the sensor 35 moves away from the sensor switch 34. The sensor switch 34 senses this change in relative position and controls the light 31 to turn on, providing immediate illumination for the user to use the rescue knife in dark environments.

[0071] The illumination lamp 31 is turned on and off based on the relative position of the inductive switch 34 and the sensor 35, eliminating the need for manual operation by the user. This simplifies the operation process and avoids the hassle of searching for the switch in emergency or dark environments. Simply pulling the knife body 1 out of the sheath 4 automatically turns on the illumination function, making the use of the rescue knife smoother and more efficient. Simultaneously, the automatic control of the illumination effectively saves battery power 32, extending the overall battery life of the illumination component 3. This ensures that the illumination lamp 31 has sufficient power to operate normally when illumination is truly needed, further enhancing the practicality of the illuminated rescue knife in actual rescue scenarios.

[0072] In this embodiment, the inductive switch 34 is a Hall effect sensor, and the sensing element 35 is an inductive magnet. When the rescue knife with light is inserted into the sheath 4, the inductive magnet on the sheath 4 approaches the Hall effect sensor at the front end of the handle 2. The Hall effect sensor can sense changes in magnetic field strength. Due to the change in magnetic field caused by the proximity of the inductive magnet, the Hall effect sensor outputs an electrical signal based on this change, which controls the light 31 to turn off through the connected circuit structure 33. When the rescue knife is pulled out of the sheath 4, the inductive magnet moves away from the Hall effect sensor, and the magnetic field strength changes. The Hall effect sensor senses this change again and outputs a different electrical signal, causing the circuit structure 33 to control the light 31 to turn on, thereby providing timely illumination when the rescue knife is needed.

[0073] In some embodiments, the inductive switch 34 and the sensing element 35 may also be an infrared inductive switch and a corresponding infrared reflector or a capacitive inductive switch and a corresponding metal inductive element. The working principle and specific structure of these components will not be elaborated here.

[0074] It is understood that the Hall effect sensor switches, infrared sensor switches, and capacitive sensor switches mentioned above are all technologies related to this field, and their working principles and specific structures will not be elaborated here.

[0075] Alternatively, in some embodiments, the lighting lamp 31 may also be configured with a manual switch, which the user can control by manually pressing or pushing the lighting lamp 31 to turn it on and off, thereby increasing the initiative in using the lighting lamp 31.

[0076] Since rescue knives may be used in humid environments such as underwater or rainy days, a lampshade 36 is provided on the outer periphery of the lighting lamp 31 on the handle 2 to seal the lamp 31. By integrating the battery 32 and circuit structure 33 inside the handle 2 and by using the lampshade 36, a relatively sealed and waterproof environment is created. This reduces the possibility of the lighting component 3 malfunctioning due to moisture, extends the overall service life of the lighting component 3, ensures the normal use of the rescue knife in humid environments, and improves its applicability and practicality in complex rescue scenarios.

[0077] To enhance the adaptability and flexibility of the rescue knife, a lanyard hole 23 is provided on the handle 2. During use, the user can hang the rescue knife on their waist, backpack, or other locations via the lanyard, making it easily accessible during operations. This frees up both hands and improves portability. Even if the knife slips in an emergency, it will not be lost due to the lanyard connection, reducing the risk of tool loss and ensuring the rescue knife remains functional in critical moments.

[0078] Furthermore, the handle 2 is equipped with a glass-breaking tip 21 at its tail, the radial cross-section of which gradually decreases from the head to the tail of the handle 2. The glass-breaking tip 21 expands the functionality of the rescue knife, enabling it to be used for critical operations such as breaking windows in emergencies, creating more possibilities for rescue and escape. The gradually decreasing radial cross-section of the glass-breaking tip 21 forms a pointed structure, effectively concentrating the applied force on a single point or small area of ​​the glass, increasing the pressure per unit area, making the glass easier to break, and improving glass-breaking efficiency. In addition, the glass-breaking tip 21 is located at the tail of the handle 2, conforming to ergonomics, allowing for easier force application using the strength of the arm and body when swung.

[0079] Specifically, the tail of the handle 2 is detachably connected to a tail cap 22, and the breaker head is coaxially mounted on the tail cap 22. This allows for the installation of other expansion components besides the breaker head, such as wrenches or flints, on the tail cap 22. Users can select different expansion components by replacing the tail cap 22 according to different usage scenarios and needs, thereby improving the functionality of the rescue knife.

[0080] In this embodiment of the rescue knife with illumination, the main body of the rescue knife, including the handle 2 and the sheath 4, is manufactured using injection molding. Specifically, high-strength, wear-resistant, and relatively tough engineering plastic is selected as the injection molding material. According to a pre-designed mold, molten plastic is injected into the mold cavity using an injection molding machine. After cooling and solidification, a blank of the handle 2 and the sheath 4 with precise shape and size is obtained.

[0081] After injection molding, the handle 2, sheath 4, and other related components are assembled using ultrasonic welding. Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of the two objects to be welded. Under pressure, the surfaces rub against each other, forming a fusion between molecular layers. Ultrasonic welding not only ensures a strong connection but also provides high sealing performance, allowing the rescue knife to be both waterproof and have a smooth weld appearance, without affecting the overall aesthetics and functionality of the knife.

[0082] For the internal circuitry of the rescue knife, specifically the circuit structure 33 connecting the battery 32 and the lamp 31 in the lighting assembly 3, a potting process is employed. A potting compound with good insulation, moisture resistance, and a certain degree of flexibility is selected and injected into the internal space of the handle 2 that houses the circuit structure 33, ensuring that the circuit structure 33 is completely covered. After potting, on the one hand, the circuit structure 33 is effectively protected from external moisture, dust, and other corrosive elements, improving circuit stability and sealing, and extending its service life. On the other hand, the potting compound buffers external impacts and vibrations on the circuit, preventing loosening or desoldering of circuit components due to vibration, ensuring the lighting assembly 3 operates normally and stably in various complex environments, thereby ensuring the performance stability and reliability of the entire illuminated rescue knife during actual use.

[0083] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments.
